| And apparently the toolhelp.dll.ClassFirst is not yet implemented on WINE:

Though I think it should be implemented already:

$ ll dlls/toolhelp*
| -rw-rw-r--  1 s2 s2 13 Feb 22 12:50 dlls/toolhelp.dll16
| lrwxrwxrwx  1 s2 s2 15 Feb 13 00:42 dlls/toolhelp.dll.so -> kernel32.dll.so

$ cat dlls/toolhelp.dll16 
| kernel32.dll

Looks like another reference to the same builtin module "kernel32.dll".

$ cat dlls/kernel32.dll.so | strings | grep ClassFirst
| ClassFirst
| __wine_stub_ClassFirst

Stub?

$ grep -r ClassFirst dlls/kernel
| dlls/kernel/toolhelp.h:BOOL16 WINAPI ClassFirst16( CLASSENTRY *pClassEntry );
| dlls/kernel/toolhelp.spec:#69 pascal -ret16 ClassFirst(ptr) ClassFirst16
| dlls/kernel/toolhelp.spec:69 stub ClassFirst
| Binary file dlls/kernel/kernel32.dll.so matches
| Binary file dlls/kernel/toolhelp.spec.o matches

Stub, but lets go further:

$ grep -r ClassFirst dlls/*/*.c
| dlls/user/class.c: *            ClassFirst (TOOLHELP.69)
| dlls/user/class.c:BOOL16 WINAPI ClassFirst16( CLASSENTRY *pClassEntry )

So, it's implemented, only in another module, in "user32.dll".  I don't know
whether it can be forwarded at imports level.  Probably it cannot.  Kernel32
must not depend on User32, I guess.

Then it perhaps can be imported during run-time linking via GetProcAddres().

Or maybe the situation will change in nearest future as I saw AJ doing some
module-load-rewrite recently. :)
